These have heen constructed se hnl they are useful only under the particular conditions' for which they nre adapted. Therefore in order i0 be prepared te meet :ill er' the various requireinens el eleeiricnl installations e manufacturer innst ineke, e dealer 0r cenractor must ezn'ry in sier-li und an installer er wire-nien nnis lelie le the joh en excess number ei' all el' the severzil varieties of mein line :nifl branch line hnses het might be needed for eoinpleing ille wei-lr. rl"his is costly for Ihe eentracler :and adds lnhnr lo he installer. l `nrihernime, il. frequently happens that ille slee.; is inminplete and the particular cii-eu that is Wanted is not; et hand unil ennne he el)- l/ziinecl when needed.

Each ot'. the raised portions of the e/ tap straps is provided with a screw fa/ ened cap 14 by means of which a bared /section of a line Wire may be clamped to the strap. The tap base shown in Figs. 5 and 6 has vatap strap with a. capped raised portion in an outside Wire channel, which enables' this block to be located between and connected With tivo branch units in such manner that the branch units may be electrically connected with one outside 'wire of the main line, When one of these blocks is turned one Way, as shown at the top of Fig. 1, and when turned'around. it enables two branch units to be connected with the other outside Wire ci' the main line, as shown at the bottom of F ig. 1. The capped portion of the tap strap of the base shoivn in Figs. 7 and 8 rises in the middle Wire channel. This enables a branch unit or two branch units to be electrically connected with vthe middle wire of the main line, as shown at the center of Fig. l. For connecting two opposite branch units with both outside Wires the tap base may be provided with tap straps that rise in the path of th two outside Wire channels of the base, as shown in Figs. 9 and 10.

The tap straps are cheaply formed and are easily inserted in the recesses in the readily obtained porcelain bases, and When the individualA single line'bases are joined together to form multiple lline branch bases and -the tap straps are fastened between them the assemblage forms a complete unitary service cutqout With lthe parts to be electrically connected with the line Wires in convenient position and proper relation, and all of the other parts suitably insulated.

The invention claimed is? 1. Anelectric current carrying device comprising a plurality of individual single line cut-out bases of insulating material, each bearing tWo conducting circuit wire terminals, means for mechanically joining Ysaid single line cut-out bases, a plurality of' individual single line tap bases of. insulating material, each bearing a conducting tap 'strap, each of which straps has means for mechanicaland electrical connection With a e circuit Wire terminal of a cut-out base and for mechanical and electrical connection with a main line Wire.

9. An electric current carrying device comprising a plurality of single wire tap units, a conductor and connecting member mounted von each of the said single wire tap units, a plurality of -single wire line units,

10. An electric current carrying device 'comprising e plurality of single Wire tap units, a current carrying and connecting member on each of the seid single wire tap units, means for-connecting n 11min line' wire to each of the said current carrying and connecting members, :i plurality of' single wire line units, means for connecting the said single wireline units together, terminals on each of the seid single wire line units adapted to receive a circuit opening device, and

-meens for connectingthe said current carvrymg and connecting member of each of the said single Wire tap units to-one of' the terminals of one of the said single Wire line unite. v v

ll. An electric current carrying device comprising e plurality'of single Wire tap units7 e conducting member on each of the said single Wire tap units extendingthrougb :ind projecting beyond vthe opposite Sides of the seme, means for electrically connecting u main line Wire to each of the said conducting members, e plurality ofA single Wire line units, means for connecting the seidvsingle `Wire line unitsv together, and terminals mounted on each of the seid single Wire line units and adapted to receive-a circuit opening device, the said projecting ends of the seid conducting members being adapted to be electrically connected t0 the terminals of the circuit opening devices mounted on the seidsingle wire line units and thus mechanically connectthe units together.
